Some clarification, I did not do the authors proposed code fix on the live site so that we could rule out the current problem of not being able to access 90% of the dashboard. Having very limited access to the dashboard because of a plugin is a huge issue. As for Woocommerce Mega menu being a niche, not sure why that is an issue. My problem is that while I have Pricing Deals for Woocommerce plugin active I can’t access most of the tabs in the dashboard. I deactivate his plugin and I was able to use my dashboard. Did the remove and then add all of the plugins back in one at a time on the dev site and it was Pricing Deals for Woocommerce causing the problem. The author said he only support Woocommerce, and not any of their plugins or their themes. Seems very misleading when you support Woocommerce but none of their plugins or themes. Just my heads up to people when there making a purchasing choice.
